Description
Technical Field
[0001] This utility model relates to the field of automotive sensor processing, and in particular to a size detector for automotive sensor processing. Background Technology
[0002] With the rapid development of the automotive industry, the safety, comfort, and intelligence of vehicles are constantly improving. As a key component of automotive electronic control systems, the performance and quality of automotive sensors directly affect the overall operation of the vehicle. The dimensional accuracy of automotive sensors is crucial for their normal operation and good compatibility with other automotive components. Dimensional deviations can lead to difficulties in sensor installation and inaccurate signal transmission, thus affecting the vehicle's safety performance and user experience. Therefore, developing a high-precision, high-efficiency dimensional detector for automotive sensor manufacturing that can adapt to various size specifications is of significant practical importance.
[0003] Currently, traditional dimensional inspection methods, such as manual measurement, are not only inefficient and labor-intensive, but also susceptible to human error, leading to inaccurate and inconsistent results. Existing automated inspection equipment operates on assembly lines, requiring sensors to be inspected one by one, resulting in slow inspection speeds. Furthermore, when a sensor with non-compliant dimensions is detected, inspection may be halted until a worker removes the problematic sensor before continuing, significantly impacting efficiency. Therefore, there is an urgent need for a dimensional detector for automotive sensor processing that improves inspection efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a size detector for automotive sensor processing in order to solve the above-mentioned problems.
[0005] This utility model achieves the above objectives through the following technical solutions:
[0006] A dimension detector for automotive sensor processing includes: a worktable, a support column fixedly mounted on the back of the worktable, a servo motor fixedly mounted at the bottom end of the support column, a rotating shaft connected to the output end of the servo motor, the rotating shaft rotatably passing through the support column, and a rotating plate fixedly connected to the outer wall of the top end of the rotating plate, cylinders fixedly mounted on the top surfaces of the two ends of the rotating plate, cross plates fixedly connected to the outer walls of the output ends of the two sets of cylinders, telescopic detection structures provided at the four front ends of the cross plates, clamping structures provided at the bottom ends of the telescopic detection structures, and dimension detection plates provided on the top surface of the worktable corresponding to the clamping structures.
[0007] Furthermore: the telescopic detection structure includes a fixed cylinder fixedly installed on the top surface of the cross plate. The fixed cylinder is cylindrical and contains a first spring. The bottom end of the first spring is attached to the top surface of the first limiting plate. A moving rod is fixedly installed on the bottom surface of the first limiting plate, and a clamping structure is fixedly connected to the bottom surface of the moving rod.
[0008] Furthermore: the movable rod slides through the front end of the cross plate, and the cross section of the movable rod is square. The area of the first limiting plate is larger than the cross section area of the movable rod but smaller than the cross section area of the fixed cylinder.
[0009] Furthermore: the clamping structure includes a clamping top plate fixedly installed on the bottom surface of the moving rod, the clamping top plate contains a second spring, the front end of the second spring is fixedly connected to the back of the second limiting plate, the front of the second limiting plate is fixedly connected to a pull rod, the end of the pull rod away from the second limiting plate is fixedly connected to a clamping plate, and the clamping plate cooperates with the vertical plate on the bottom surface of the clamping top plate to clamp the sensor.
[0010] Furthermore: the pull rod slides through the front end of the clamping top plate and has a square cross-section; the cross-sectional area of the second limiting plate is larger than the cross-sectional area of the pull rod but smaller than the cross-sectional area of the clamping top plate.
[0011] Furthermore: the size detection plate is detachably installed on the top surface of the workbench by screws, and slots of the same size as the clamping plate and the vertical plate are provided at the positions corresponding to the clamping plate and the vertical plate, so that the clamping plate and the vertical plate can move up and down.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a cross plate, multi-station sensor detection can be realized, improving detection efficiency. By setting a telescopic detection structure, when the sensor is being dimensionally detected, the drive cylinder moves the cross plate downward, and the sensor held below the clamping structure moves downward at the same time. If it enters the size detection plate on the top surface of the workbench, it means the size is qualified; if it does not enter the size detection plate, it means the size is unqualified. At this time, the sensor comes into contact with the size detection plate, and the sensor pushes the moving rod at the top of the clamping structure upward, pushing the first spring inside the fixed cylinder to compress it, which plays a buffering role for the sensor and avoids collision between the sensor and the size detection plate, thus preventing damage. The operator records the sensor with unqualified size. After the detection is completed, the servo motor rotates, driving the rotating plate to rotate 180 degrees to detect another set of sensors. At this time, the operator removes the sensor with unqualified size from the back of the workbench and replaces it with the sensor to be tested. This structure realizes the function of continuous detection, and the equipment will not stop when encountering a sensor with unqualified size. Combined with the multi-station design, it can significantly improve detection efficiency. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings:
[0024] like Figures 1-5As shown, a dimension detector for automotive sensor processing includes: a worktable 1, a support column 2 fixedly mounted on the back of the worktable 1, a servo motor 3 fixedly mounted at the bottom of the support column 2, a rotating shaft 4 connected to the output end of the servo motor 3, the rotating shaft 4 rotatably passing through the support column 2, and a rotating plate 5 fixedly connected to the outer wall of its top end; cylinders 6 fixedly mounted on the top surfaces of both ends of the rotating plate 5; cross plates 7 fixedly connected to the outer walls of the output ends of the two sets of cylinders 6; telescopic detection structures are respectively provided at the four front ends of the cross plates 7; clamping structures are provided at the bottom ends of the telescopic detection structures; and dimension detection plates 8 are provided on the top surface of the worktable 1 corresponding to the clamping structures. By setting the cross plates 7, multi-station sensor detection can be realized, improving detection efficiency. By setting the telescopic detection structure, when performing dimension detection on the sensor, the drive cylinder 6 drives the cross plates 7 to move downward, and the sensor clamped below the clamping structure... Simultaneously moving downwards, if the sensor enters the dimension detection plate 8 on the top surface of workbench 1, it indicates that the dimension is qualified; if it does not enter the dimension detection plate 8, it indicates that the dimension is unqualified. At this time, the sensor comes into contact with the dimension detection plate 8, and the sensor pushes the moving rod 12 at the top of the clamping structure to move upwards, pushing the first spring 10 inside the fixed cylinder 9 to compress it, which plays a buffering role for the sensor and avoids collision between the sensor and the dimension detection plate 8, thus preventing damage. The operator records the sensor with unqualified dimensions. After the test is completed, the servo motor 3 rotates, driving the rotating plate 5 to rotate 180 degrees to test another set of sensors. At this time, the operator removes the sensor with unqualified dimensions from the back of workbench 1 and replaces it with the sensor to be tested. This structure realizes the function of continuous testing, and the equipment will not stop in the middle when encountering a sensor with unqualified dimensions. Combined with the multi-station design, it can significantly improve the testing efficiency.
[0025] In some embodiments, the telescopic detection structure includes a fixed cylinder 9 fixedly installed on the top surface of the cross plate 7. The fixed cylinder is used to accommodate the movement of the first spring 10 and the moving rod 12. The fixed cylinder 9 is cylindrical and has the first spring 10 inside. The first spring 10 is used to buffer the sensor and prevent the sensor from being damaged due to rigid contact with the size detection plate 8. The bottom end of the first spring 10 is attached to the top surface of the first limiting plate 11. The area of the first limiting plate 11 is set to be larger than the cross-sectional area of the moving rod 12 and smaller than the cross-sectional area of the fixed cylinder 9. This setting can prevent the first limiting plate 11 from coming out of the fixed cylinder 9 and affecting the detection. The moving rod 12 is fixedly installed on the bottom surface of the first limiting plate 11. The moving rod 12 slides through the front end of the cross plate 7 and has a square cross-section. The square moving rod 12 can prevent the moving rod 12 from rotating when it moves up and down inside the fixed cylinder 9, which would cause the position of the sensor clamped below to rotate and shift, making it unable to correspond with the size detection plate 8 and thus unable to detect the size. The bottom surface of the moving rod 12 is fixedly connected to a clamping structure.
[0026] In some embodiments, the clamping structure includes a clamping top plate 13 fixedly mounted on the bottom surface of the movable rod 12. A second spring 14 is housed inside the clamping top plate 13 to provide clamping power for the sensor. The front end of the second spring 14 is fixedly connected to the back of the second limiting plate 15. The second spring 14 is located between the second limiting plate 15 and the inner wall of the clamping top plate 13. The movement of the second limiting plate 15 can compress and release the second spring 14 to achieve the function of clamping the sensor. A pull rod 16 is fixedly connected to the front side of the second limiting plate 15. The pull rod 16 slides through the front end of the clamping top plate 13 and has a square cross-section. The square design of the pull rod 16 can prevent the pull rod 16 from collapsing when clamping the sensor. The rotation causes the sensor to be incorrectly clamped, affecting subsequent detection. This setting serves as a limit. The cross-sectional area of the second limiting plate 15 is set to be larger than the cross-sectional area of the pull rod 16 but smaller than the cross-sectional area of the clamping top plate 13. This setting can prevent the second limiting plate 15 from coming out of the clamping top plate 13 and affecting the clamping of the sensor. The end of the pull rod 16 away from the second limiting plate 15 is fixedly connected to the clamping plate 17. The clamping plate 17 cooperates with the vertical plate on the bottom surface of the clamping top plate 13 to clamp the sensor. Pulling out the clamping plate 17 places the sensor between the clamping plate 17 and the vertical plate. Releasing the clamping plate 17 allows the sensor to be clamped by the tension of the second spring 14.
[0027] In some embodiments, the size detection plate 8 is detachably mounted on the top surface of the workbench 1 by screws, which can be replaced for different models of sensors, improving the adaptability of the detector. Slots of the same size as the clamping plate 17 and the vertical plate are provided at the positions corresponding to the clamping plate 17 and the vertical plate, allowing the clamping plate 17 and the vertical plate to move up and down. The slots can prevent interference between the clamping plate 17 and the vertical plate and the size detection plate 8 when they descend, ensuring that the sensor can completely enter the size detection plate 8 to complete the size detection.
[0028] The servo motor 3 used in this invention is a Mitsubishi MR-JE-40A model from the MR-JE series, with a power of 400W, capable of achieving precise fixed-angle positioning. The cylinder 6 used in this invention is a Festo ADVU-100-800-AP model from the ADVU-ISO series, with a cylinder diameter of 100mm and a stroke of 800mm, suitable for pushing and positioning components in automotive sensor processing equipment.
[0029] Working principle: In use, pulling the clamping plate 17 outward causes the pull rod 16 to move outward from the clamping top plate 13. The second limiting plate 15, which is fixedly connected to the pull rod 16, causes the second spring 14 to stretch, placing the sensor between the clamping plate 17 and the vertical plate. Releasing the clamping plate 17 allows the sensor to be clamped by the tension of the second spring 14. After installing the sensors in sequence, drive the servo motor 3 to drive the rotating shaft 4 to rotate the rotating plate 5 180 degrees, turning the installed sensor directly above the dimension detection plate 8. At this time, drive the cylinder 6 to move downward, causing the cross plate 7 to move downward, and the sensor to move downward. If the sensor enters the dimension detection plate 8 on the top surface of the worktable 1, it indicates that the size is qualified; if it does not enter the dimension detection plate 8, it indicates that the size is qualified. If the dimensions are found to be non-compliant, the sensor will contact the dimension detection plate 8. The sensor will push the moving rod 12 at the top of the clamping top plate 13 to move upward, and the first limit plate 11 will move upward, pushing the first spring 10 inside the fixed cylinder 9 to compress it, which will buffer the sensor and prevent it from colliding with the dimension detection plate 8 and causing damage. The operator will record the sensor with non-compliant dimensions. After the test is completed, the cylinder 6 will reset and drive the sensor to move upward. The servo motor 3 will drive the rotating shaft 4 to rotate, causing the rotating plate 5 to rotate 180 degrees in the opposite direction to reset. The other set of sensors will then be tested. At this time, the operator will remove the sensor with non-compliant dimensions from behind the workbench 1 and replace it with the sensor to be tested, completing the entire testing process.
[0030] The servo motors and cylinders are all standard parts or obtained through conventional experimental methods, so they will not be described in detail here.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of this utility model as claimed.
